The relation between metabolic demand and maximal oxygen consumption during exercise have been investigated in different areas of knowledge. In the health field, the determination of maximal oxygen consumption (VO2max) is considered a method to classify the level of physical fitness or the risk of cardiocirculatory diseases. The accuracy to obtain data provides a better evaluation of functional responses and allows a reduction in the error margin at the moment of risk classification, as well as, at the moment of determination of aerobic exercise work load. In Brasil, the use of respirometry associated to ergometric test became an opition in the cardiorespiratory evaluation. This equipment allows predictions concerning the oxyredutase process, making it possible to identify physiological responses to physical effort as the respiratory threshold. This thesis focused in the development of mathematical models developed by multiple regression validated by the stepwise method, aiming to predict the VO2max based on respiratory responses to physical effort. The sample was composed of a ramdom sample of 181 healthy individuals, men and women, that were randomized to two groups: regression group and cross validation group (GV). The voluntiars were submitted to a incremental treadmill test; objetiving to determinate of the second respiratory threshold (LVII) and the Peak VO2max. Using the método forward addition method 11 models of VO2max prediction in trendmill were developded. No significative differences were found between the VO2max meansured and the predicted by models when they were compared using ANOVA One-Way and the Post Hoc test of Turkey. We concluded that the developed mathematical models allow a prediction of the VO2max of healthy young individuals based on the LVII

The aim of this study is the labour market at Natal Metropolitan Region with emphasis in occupations and incomes that took place at the nineties. The definition of its chronological boundaries passed by verification of existence of evident socio-spatial impacts for output, occupation and income in national economy, with rebounds in all national territory, conditioned by institutional and socio-economical transformations which marked Brazilian insertion to capital flows and commodities globalization movement that took place at the cited decade. It has been shown that such impacts did not distributed themselves equally between diverse spatial levels (great regions, federate unities, municipalities) because of historical specificities in each place in terms of output structures and organization of distinct social agents. Having as its basis the Marxist perspective, it tackled theoretically occupations and incomes, transformations in labour universe occurred at world level, mainly in most urbanized areas, and following that to focus changes occurred in Brazilian society related to the search for competitive insertion in global economy during the period regarded. Special attention was gave to Natal Metropolitan Region, because it was historically a concentration area for investments, productive structure, people, occupations and incomes generated/appropriated in Rio Grande do Norte State. The basic data sources for research were the demographic Census (micro data) made by the Instituto Brasileiro de Geografia e Estatística (IBGE) intending to present the structure and the labour market dynamics, having as basis: 1) traditional indicators about labour market; 2) sectors of economic activities and 3) social positions and classes segments. One of the purposes is the demonstration that occupations and incomes keep relation with the restructuring which occurred in each specific sector during the period. Other purpose is to make explicit the factors which bear the participation of distinct segments in production or service execution that make possible the different participation in income distribution. Results are revealing the increasin precariousness in labour market, enlargement of occupations in tertiary sector and greater concentration of average incomes in the social segments which were owners of the greatest capital allowances between residents in Natal Metropolitan Region during the nineties

The aim of this thesis was to investigate the evolution of the socio-occupational status in Rio Grande do Norte from 2001 to 2008, based on the characterization of the socio-economic status of this State from the analysis of labor market norte-rio-grandense . The study, specifically, drew a comparison between the dynamics of the labor market in Rio Grande do Norte and the capital city, Natal. From this perspective, the purpose was to make a relationship between the social division of labor and its effects on the socio-spatial division, represented in the "macro scale" by the federal unit and the "micro level" for the capital; locus of economic and population concentration. The collection of data on the labor market had as a major source PNAD/IBGE, characterizing the labor market in many ways: people of working age, economically active population and employed and unemployed people, classified by age, sex, color, education, income and social protection condition. However, as for the socio-occupational division, we follow the methodology used by the research group on national television, based in IPPUR /UFRJ, called Monitoring of the Metropolis," which rallied twenty-four groups that aggregate the occupations found in the PNAD/IBGE, in eight groups of socio-occupational categories, according to the similarity between them. It was used in the socio-spatial cutting two relevant discussions, which are inter-related and were characterized as crucial points in developing the research problem: the former was related to the influence of the hegemony of merchant capital in the labor market in Rio Grande North and, the latter, it referred the socio-economic relations between the territory and the variable occupation. Lastly, the results all indicated that in Rio Grande do Norte, as a peripheral state, has suffered the devastating influence of the hegemony of capital purely commercial basis, where "wealth" of capitalism is generated through the sphere of mere movement of goods and services rather than a productive process due to the social relations of production more advanced. We have a little advanced economic structure, with a tertiary sector that has propagated under-employment or disguised unemployment. Similarly, the agricultural sector has been presented as an example of greater social degradation of working conditions in the state. The secondary sector, in turn, also was not behind this uncertainty; on the contrary, confirmed that condition, with poor levels of income, low education of the workforce and a high degree of social helplessness, even in the state capital, space full urban area, which although always appear with a favorable condition compared to Province, in practically most of the variables studied, was also reflected at the same time the author of a structurally underdeveloped condition

This study received the title THE JUVENILE EMPLOYMENT IN THE THRESHOLD OF THE XXI CENTURY: study starting from RAIS and of the programs of youths' insert in the labor market of Natal/RN . It presents as main objective to investigate, starting from the officials data of the Ministério do trabalho e emprego - MTE and of the federal and state government programs, the evolution of the formal employment for youths and the difficulties that leads the success of the returned initiatives the youths' insert in the formal market of work in Brazil and in Rio Grande do Norte, in the period from 2000 to 2004. To accomplish the research, it prioritizes the study of the evolution of the formal employment starting from the data of the MTE as form of diagnosing the formal market of the juvenile work. Search a descriptive way to identify the first results of the programs Primeiro Emprego- PPE (federal) and Primeira Chance - PPC (state), to interpret and to identify the existent gaps among the proposal initial of those programs and the first results obtained in the city of Natal. The research has character no-probability and it applies closed questionnaires for youths assisted by the programs. Were interviewed the local representatives of PPE and PPC, besides representatives of the organized civil society all through open structured interview, covering a total of 103 interviews. The results demonstrated that while PPC (state) obtained success inserting youngs, the PPE (federal) just got to insert 1,5% of the amount subsidized by the state program in Natal. That situation demonstrates a clear preference of the companies for PPC (state), in detriment of the federal program

This study aims to verify the impact of the Bolsa Família Program (BFP) in income and school attendance of poor Brazilian families. It is intended to also check the existence of a possible negative effect of the program on the labor market, titled as sloth effect. For such, microdata from the IBGE Census sample in 2010 were used. Seeking to purge possible selection biases, methodology of Quantilic Treatment Effect (QTE) was applied, in particular the estimator proposed by Firpo (2007), which assumes an exogenous and non-conditional treatment. Moreover, Foster- Greer-Thorbecke (FGT) index was calculated to check if there are fewer households below the poverty line, as well as if the inequality among the poor decreases. Human Opportunity Index (HOI) was also calculated to measure the access of young people / children education. Results showed that BFP has positively influenced the family per capita income and education (number of children aged 5-17 years old attending school). As for the labor market (worked hours and labor income), the program showed a negative effect. Thus, when compared with not benefiting families, those families who receive the BFP have: a) a higher family income (due to the shock of the transfer budget money) b) more children attending school (due to the conditionality imposed by the program); c) less worked hours (due to sloth effect in certain family groups) and d) a lower income from work. All these effects were potentiated separating the sample in the five Brazilian regions, being observed that the BFP strongly influenced the Northeast, showing a greater decrease in income inequality and poverty, and at the same time, achieved a greater negative impact on the labor market

This study aims to analyze how IFRN s process of interiorization contributes to endogenization of local and territorial development, more precisely in terms of graduates absorption into the labor market, form of inclusion and increase of income and welfare. The research premise is that the policy of interiorization and expansion of professional and technology education, by decentralizing opportunities, create a differential for the educational and professional trajectory of part of the graduates. This training, however, retain a relative connection with the productive potentialities in the coverage territories. This study includes a review of the literature on education and labor market and a discussion about the role of technical and professional formation for the local development versus the logic of the free market, considering the expansion of public spending for this purpose. For this study two sets of information and data have been collected primarily, with qualitative and quantitative nature. The research with qualitative focus, entitled Pesquisa de Avaliação da Expansão (PAEX), is constituted by series of open interviews applied to institutional representatives, with the purpose of knowing aspects of the interiorization repercussion in the local development process. The research designed to quantity analysis, entitled of the Pesquisa de Acompanhamento de Egressos (PAE), have been put in practice by applying online questionnaire with closed questions to IFRN s former students, aiming to know the form of insertion of the graduates in the labor market and the formation capacity of increasing the welfare, among other things. Empirical data and information fully confirmed the hypothesis of this study, for they really demonstrated that the expansion policy decentralizes opportunities and constitutes an important differential for the professional trajectory of a significant portion of the graduates. However, the graduates employability in the labor market in their territories of coverage is below expectations, due to structural problems of the local economy related to scarcity of jobs, difficulty in wage growth and in professional development. Complementarily, it has been observed institutional difficulties related to the recent implantation process of the policy of professional and technical education in the various campuses of the Institution

Foram ajustadas 7239 curvas de lactação de vacas Caracu, controladas semanalmente entre os anos de 1978 a 1988, pertencentes à Fazenda Chiqueirão, Poços de Caldas, MG. As funções utilizadas foram a linear hiperbólica (FLH), a quadrática logarítmica (FQL), a gama incompleta (FGI) e a polinomial inversa (FPI). Os parâmetros foram estimados por meio de regressões não lineares, usando-se processos iterativos. A verificação da qualidade do ajuste baseou-se no coeficiente de determinação ajustado (R²A), no teste de Durbin-Watson (DW) e nas médias e desvios-padrão estimados para os parâmetros e funções dos parâmetros dos modelos. Para a curva média, os R²A foram superiores a 0,90 para todas as funções. Bons ajustes, baseados nos R²A>0,80 foram obtidos, respectivamente, por 25,2%, 39,1%, 31,1% e 28,4% das lactações ajustadas pelas funções FLH, FQL, FGI e FPI. de acordo com o teste de DW, bons ajustes foram proporcionados para 29,4% das lactações ajustadas pela FLH, 54,9% pela FQL, 34,9% pela FGI e 29,6% pela FPI. Para ambos os critérios, a FQL foi superior às demais funções, indicando grande variação nas formas das curvas de lactação geradas pelos ajustes individuais. Curvas atípicas foram estimadas pelas funções, com picos ocorrendo antes do parto e algumas vezes após o término da lactação. Todas as funções apresentaram problemas quando ajustaram dados individuais.

O objetivo neste estudo foi avaliar diferentes modelos ajustados às respostas de ganho de peso obtidas em experimento com aves da linhagem ISA Label no período de 1 a 28 dias de idade. Foram utilizados 480 pintos de ambos os sexos, distribuídos em delineamento inteiramente casualizado, em arranjo fatorial 4 X 2 (níveis de lisina X sexo), com três repetições, com 20 aves por unidade experimental. Uma ração basal foi formulada para atender às exigências das aves, exceto em lisina. Essa ração foi suplementada com L-lisina HCl em substituição ao ácido L-glutâmico, resultando em rações experimentais isonitrogênicas e isoenergéticas contendo 0,85; 0,97; 1,09 e 1,21% de lisina digestível. As respostas de ganho de peso foram ajustadas de acordo com os níveis de lisina da ração pelos modelos Linear Reponse Plateau (LRP), segmentado de duas inclinações, polinomial quadrático e exponencial. A primeira intersecção da equação quadrática com o platô do LRP também foi utilizado para estimar o nível ótimo. Os níveis de lisina digestível estimados pelos modelos LRP, segmentado e quadrático, foram 0,999; 1,010 e 1,116%, respectivamente. Na combinação do modelo quadrático com o LRP, a estimativa da exigência de lisina digestível foi de 1,041%. O modelo exponencial proporcionou estimativa de 1,066%, considerando 95% da resposta assintótica. Com base nos custos com alimentação, esse mesmo modelo gerou estimativas de 1,000 e 1,030% quando o custo do quilograma de L-lisina HCl foi R$ 8,50 e R$ 6,50, respectivamente. Considerando as limitações de cada um dos modelos propostos, o procedimento para estimar as exigências de lisina digestível pela primeira intersecção da equação quadrática com o platô do LRP foi o mais adequado para melhorar o ganho de peso das aves quando variáveis econômicas não foram consideradas.

Atualmente, discussões a respeito da construção de uma sociedade inclusiva, ou seja, responsiva às diferenças, têm ocorrido em diversos países. de acordo com os princípios da inclusão social, a participação das pessoas com deficiência na sociedade depende de profundas transformações, cabendo à sociedade prover os suportes necessários para que esses indivíduos tenham acesso a todos os recursos disponíveis no meio social e, além disso, ao convívio de maneira não-segregada. Uma questão importante, nesse sentido, é a elaboração de políticas públicas no âmbito do trabalho voltadas para pessoas com deficiência. Embora o acesso ao trabalho seja considerado um dos principais direitos civis dos indivíduos, as pessoas com deficiência ainda encontram diversas barreiras para ingressar no mercado profissional. Partindo dessas afirmações, este artigo teve como objetivo discutir alguns dos principais aspectos das políticas de emprego adotadas nos Estados Unidos, na União Europeia e no Brasil para favorecer a inserção desses indivíduos no mercado de trabalho. Para tanto, três documentos legais, sendo um Nacional, um procedente dos Estados Unidos e outro, da União Europeia, foram analisados quanto aos itens: a) ano de publicação do documento; b) objetivos; c) definição de deficiência; e d) estratégias de inserção da pessoa com deficiência no mercado de trabalho. A partir das considerações realizadas, pode-se dizer que existem avanços e divergências nas políticas de emprego e que estas estão relacionadas às particularidades de cada um dos contextos; no entanto, existe uma preocupação comum em garantir à pessoa com deficiência o ingresso na atividade profissional.

This work was developed in the extent of the Post Graduation Program in Social Service of the Federal University of Rio Grande do Norte. It talks about the process of inclusion of the disabled people in the Job market in Mossoró-RN, bringing for the academic debate relevant thematic for the Brazilian society, for the profession of Social Service and similar areas and for the people with deficiency. It has the objective to apprehend the determiners that make possible the process of the disabled people's inclusion in the Job market in Mossoró, having as parameter the National Politics for the Integration of People Bearers of Deficiency. The critical theoretical perspective is backed in Marx's ideas for the understanding concerning the work, as well as in Pochamann, concerning the job market, regarding the exclusion/inclusion category is based in Martins, Yasbek and Sposati and on deficiency in the National Politics for the Integration of the Disabled People. The research is of qualitative nature and it took as subjects 26 (twenty-six) people, being 09 (nine) people with deficiency, inserted in the formal job and regulated market, and 17 (seventeen) managers of private companies and public institutions of the city of Mossoró-RN. For the collection of data we used techniques of nonsystemic observation, semi-structured interview and documental analysis. The results of the research mark that any modality of the human workforce used in the current context, they are functional to the capitalism and they move forward towards exploration, alienation and subordination of the work to the capital; the National Politics for the Integration of the People with Deficiency expresses and reproduces the contradictory dynamics of the class society, it reflects the neo liberal shades through the selectivity and of the articulation among the federated beings and organizations of the civil society for its operational system; there is a misproportion between the percentages of the quotas and the amount of people with deficiency inserted in the job market, just corresponding to a tiny numeric magnitude; the developed activities are of low social status and it is expressive the amount of workers that receives between one and two minimum wages. These data drive us to infer that the mentioned politics make possible, partly, the inclusion of the disabled people in the job market, though, such inclusion is executed in the selective or focused dimensions, marginal, precarious and unstable
